HART A. STODDARD,

EENNSYLVA'NIA.

Application filed December 4,i1912.

To all whom it may concern:

Be it known that I, HART A. STODDARD, a citizen of the United States, residing at the city of Fhiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improve of which the following.

ments in Wall-Boxes, is a specification.

The invention relates to wall boxes such as are mounted in the wall and used to contain electric switches and similar specialties.

The principal object of the present invention is to provide a comparatively simple, satisfactory and inexpensive wall box which can be quickly and conveniently extended as desired without requiring the use of tools or screws, which are likely to be disconnected and lost, and which presents a substantially flush or smooth end wall or walls.

The invention will be claimed at the end hereof but will be first described in connection with the embodiment of it chosen for illustration in the accompanying lrawings "forming part hereof and in which Figure 1, is an'end view of a wall box embodying features of the invention. Fig. 2, is a similar VlGW illustrating a second section applied to the section shown in Fig. 1, in order to increase the capacity of the box. Fig. 3, is a sectional view taken on the line 3-8, of Fig. 2. Fig. 4, is a perspective view of an end plate illustrating features of the invention. Fig. 5, is a sectional view on the line 5--5, of Fig. 1, and Fig. 6, is a similar view: on the line 66, of Fig. 2.

Each box section has formed through its end wall a hole 1, and the end Wall is provided with an indentation 2, extending from its margin. inward.

3, is a pin arranged to penetrate the hole 1, and to project inwardly from the wall. The pin 3, is connected with the wall by a connection 4. This connection 4:, may beof spring or other metal and, as shown, it is connected with the wall by a rivet 5, or its equivalent. Each section is also provided at the edge of its end wall with a projecting finger 6, adapted to cooperate'with and to enter the indentation 2, and each section is also provided at the edge of its end wall with a lug or ear 7 having a perforation 8, that receives the inner end of the pin 3. The wall box proper is shown in Fig. 1. The side wall 9, is provided with fingers 6, that or rnrnannnrnia, ELECTRIC COMPANY, or PHILADELPHIA, rEnNsYLvAnrA, A.

takeinto indentations2, and rivets 10, pass through itheholes 1 and 8. The other side wall 11', is detachably held to'plac e by {in gers and corresponding indentations and by pins 3, passing through the holes 1 and 8. The fingers and indentations prevent relativennovement' of the parts which are secured together by the pins 3. To enlarge the capacity of the box the pins 3, are withdrawn from the holes 1 and 8. This can be done without the use of tools as by means of the fingers. For this purpose depressions '12, may be made 1n the end walls adjacent to the connections 1. The side 11, is then withdrawn and another section applied as shown in Fig. 2. The pins 3, serve to secure these sections to place. If the ends of the pins arebeveled as shown at 13, in Fig. 6, they operate like spring catches when the second section is applied. After the desired number of sections have been assembled, the side section 11, is applied as shown in Fig. 2. Since the connections 41, may lie comparatively flat on the end walls, it follows that the latter are comparatively smooth and free from projections. Evidently tools are not required when assembling the various parts and the pins may not become detached and therefore are neither lost nor mislaid. Of course the box may be used as shown in Fig. 1, or it may be enlarged to theext-ent as shown in Fig. 2, or to any extent.

What I claim is:

1. A wall box comprising the combination of box section, an end wall for the section having a hole through it and having an indentation extending to its margin, a pin arranged to slide endwise through said hole and to project from the wall, a yielding bar connection connecting one end of the pin and the wall, and a second box section pro-v vided at its edge with a rigid finger adapted to said indentation and with a lug or car provided with a hole for the reception of the lee end of the pin.

2. A wall box comprising the combination of a box section, an end wall for the section having a hole through it and having an indentation extending to its margin, a. bevel-ended pin arranged to slide endwise through said hole and to project from the wall, a yielding bar connection connecting one end of the pin and the wall, and a secrigid finger adapted to said indentation and Wit a lug or ear the reoeptionof t 3.
